firewire: nosy: switch from 'pci_' to 'dma_' API

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated in 'add_card()', GFP_KERNEL can be used because
this flag is already used a few lines above and no lock is taken in the
between.

While at it, also remove some useless casting.
